Yes — OpenClaw can build, launch and manage your cold email campaigns in WarmySender, all in plain language, through the same 78-tool connection Claude, ChatGPT, Cursor, Codex, OpenClaw, and Hermes Agent share. You ask in OpenClaw’s chat, on your own machine or server. It never sends a message itself and can never raise a limit: it writes the campaign and hands it to WarmySender’s scheduler, which paces every email, LinkedIn, Instagram and WhatsApp action inside safe limits no matter who is driving. Connecting and disconnecting accounts stays in the app.
OpenClaw is a self-hosted agent: it runs on a machine you control, and you talk to it from its own chat rather than a vendor’s window. It connects with two commands — one registers the server with sign-in enabled, the second opens a WarmySender sign-in in your browser. OpenClaw ignores static headers while sign-in is on, so no key is ever stored. Cold email through OpenClaw suits a team that wants the agent on its own machine or server rather than in a vendor’s chat window. Register WarmySender once with two commands; the sign-in runs in your browser and OpenClaw stores no key.
Every "can" below stands on a real tool in the WarmySender connection. Every "cannot" is not a setting — there is simply nothing an agent can call that does it.
| Can / cannot | What that means for cold email |
|---|---|
| Can | Create a multi-step campaign, edit it, and set the sending window and daily limits. |
| Can | Start, pause and resume a campaign — starting only hands it to the scheduler. |
| Can | Add prospects one at a time or in bulk, update their details, and enroll or unenroll them. |
| Can | Work from your saved email templates instead of writing every email from scratch. |
| Can | Read and add to your suppression list so the wrong people are never contacted. |
| Can | Report on every campaign and explain why nothing went out today. |
| Can | Add a branded tracking domain and check that it is set up correctly. |
| Can | Set the postal address and opt-out wording used in your email footer. |
| Cannot | Send an email itself — it writes the campaign and WarmySender’s scheduler sends at your safe pace. |
| Cannot | Raise a daily cap, a warmup stage or a domain ceiling — nothing it can call moves a limit. |
| Cannot | Connect or disconnect a mailbox — credentials never pass through an agent. |
| Cannot | Switch off the opt-out in your footer — it can change the style, never remove it. |
| Cannot | Read or reply to responses — replies stay in WarmySender’s inbox, with you. |
OpenClaw registers WarmySender from its command line and signs in through your browser — after that it can call every tool from its chat.
Run both lines; the second opens a WarmySender sign-in in your browser. OpenClaw ignores static headers while sign-in is on, so no key is ever stored.

Both routes reach the same workspace and stay inside the same safe limits. Every agent's steps live on the AI Agents hub.
Create a three-step campaign called "Agency founders" for this list, weekdays only, from my two warmed mailboxes, then start it.
Pause every campaign that uses the sales@ mailbox until Monday.
Why did the "Q4 partners" campaign send nothing yesterday?
Add these 40 people to the suppression list and take them out of any running campaign.
Build a two-step campaign from the list I give you, from my two warmed mailboxes, and report back once it has started.
OpenClaw never sends a message itself and can never raise a limit. Creating or launching a campaign only writes it and hands it to WarmySender's scheduler, which paces every email, LinkedIn, Instagram and WhatsApp action inside safe limits and a gradual ramp — the same protections that apply when a human clicks the buttons. Connecting and disconnecting accounts stays in the app. Account safety always wins.
Yes. Connect OpenClaw to WarmySender and ask in plain language, in OpenClaw’s chat, on your own machine or server — it can build, launch and manage your cold email campaigns. It never sends a message itself and can never raise a limit: it writes the campaign and hands it to WarmySender’s scheduler, which paces every email, LinkedIn, Instagram and WhatsApp action inside safe limits no matter who is driving. Connecting and disconnecting accounts stays in the app.
OpenClaw registers WarmySender from its command line and signs in through your browser — after that it can call every tool from its chat. Run both lines; the second opens a WarmySender sign-in in your browser. OpenClaw ignores static headers while sign-in is on, so no key is ever stored. The command text is: openclaw mcp add warmysender --url https://warmysender.com/mcp --transport streamable-http --auth oauth openclaw mcp login warmysender — the server address is https://warmysender.com/mcp. The steps are on this page under "Connect OpenClaw", and the full install hub for every agent is at /ai-agents.
No. Nothing an agent can call moves a limit — not a mailbox’s daily cap, your domain’s ceiling or the pace across the sending window. OpenClaw can read where you are against a limit and tell you when a pause lifts; WarmySender’s scheduler decides what actually goes out.
No. Connecting and disconnecting accounts stays in the app on purpose — a credential should never pass through an agent or a chat log. Connect the mailbox once in WarmySender; after that OpenClaw can use it.
Nothing goes out in a burst. Starting a campaign only queues it, and WarmySender’s scheduler drains that queue at your normal daily pace across your sending window, inside each mailbox’s limit and your domain’s ceiling. Pausing is one sentence and is never blocked, and everything the agent built is a normal campaign you can open, edit or delete.
OpenClaw keeps the sign-in it obtains from the browser flow that the login command opens. No API key is written to its configuration, because OpenClaw ignores static headers while sign-in is on.
Yes, as long as the one-time sign-in can be completed in a browser. WarmySender is a hosted server at https://warmysender.com/mcp, reachable from any machine, and the mailbox stays connected in WarmySender — never on the agent host.
Yes — create a key under Settings › API Keys and use the key form on the AI Agents hub, which registers the server without the sign-in flag. With sign-in on, OpenClaw ignores static headers, so pick one route or the other.
